Notes

1Omega-type doubling Delta vef(v=0) = (+)8.9E-5J(J+1). The rotational analyses by Abraham and Patel, 1970 and Abraham and Patel, 1971 are in disagreement with Prevot, Colin, et al., 1975.
2Extrapolations from v'-0 bands having v'geq 2.
3Extrapolations from v'-0 (A2 rarrow X2) and 0-v" (A2 rarrow a) bands having v' geq 1 and v" geq 2, respectively.
4Extrapolated from the 0-2 band, the only rotationally analysed band. The lower-state vibrational numbering of Chakravorty, Abraham, et al., 1973 has been increased by 1 Vasudev and Jones, 1976.
5Band heads observed, but no details given Vasudev and Jones, 1976.
6Omega-type doubling Delta vef(v=0) = +0.00031J(J+l) Vasudev and Jones, 1976.
